HEAT INSULATION PLATE RAW MATERIAL COMPOSITION, HEAT INSULATION PLATE, AND PRODUCTION PROCESS FOR HEAT INSULATION PLATE

摘要

A heat insulation plate raw material composition, a heat insulation plate, and a production process for the heat insulation plate. The components in parts by weight of the heat insulation plate raw material composition comprise: 60-80 parts of a siliceous substance, 17-28 parts of a binder, 5-8 parts of polystyrene particles, and 20-60 parts of water, wherein the binder comprises calcium oxide and/or calcium hydroxide. The tensile strength of the prepared heat insulation plate is 0.2Mpa or above, the compressive strength is 0.3Mpa or above, the bending deformation is 4mm or above, the heat conductivity coefficient is 0.055W/(m·K) or below at 25°C, the volume water absorption rate is 5.5% or below, and the fireproof grade is non-combustible, i.e., being not lower than A2 grade.
